Awstats generates every hour an awstatsMMYYYY.www.domain.nu.txt file ( I can see this on the timestamp of the files )
The problem is that jawstats speaks a different language.

jawstats wants to read a file with the name awstatsYYYYM.www.domain.nu.txt to make jawstats speak the same language as awstats I added this: "statsname" => "awstats[MM][YYYY].www.domain.nu.txt",to the jawstats config.php file but it did not help.
